Transparency and synchronization in supermedia enhanced Internet-based teleoperation

Abstract

This paper concentrates on transparency and synchronization of supermedia in Internet based teleoperation. Supermedia is used to describe the collection of all the feedback streams in teleoperations, such as haptic, video, audio, temperature and others. Transparency and synchronization are introduced and analyzed from the event-based control perspective. The concepts of event-transparency and event-synchronization for event-based control telerobotic systems are developed and their implications are studied. To illustrate those concepts and their benefits, the teleoperation of a mobile manipulator via the Internet, where haptic, video and temperature information is fed back to the operator, is discussed. Experimental results will verify the event-transparency and event-synchronization of this event-based telerobotic system.
